In matrix composing and line casting machines, wherin the released matrices drop through a guide on to an assembler belt, it is necessary for the assembler belt to travel, at such a speed, that 95 when a matrix is released from that side of the magazine which is furthest away from the assembler, and immediately thereafter a matrix is released from the side of the magazine adjacent to the assembler, the matrix first released shall always reach the assembler first. The inference to be drawn from this, more especially in the case of wide magazines and with operations performed at the usual composing speed, is that the assembler belt has to travel at a considerable speed, and that in consequence thereof, the mat- 0 side of the magazine towards the centre, and as the path of travel of the matrices from the channel at the greatest distance from the assembler is reduced by half, a reduced belt speed can be employed, or a higher composing speed can be 5 reached. In the arrangement heretofore proposed, the matrices were brought towards each other to a point below the centre of the magazine and fell through a chute into the assembler channel. This arrangement however was unsatis- 3 O factory, partly because a too strong braking action was produced owing to the matrices, after dropping off the assembler belts, having to pass through a comparatively long assembler chute, or, if the deflecting channel ofiered but slight resistance, the matrices followed each other much too quickly. The result of this was an incorrect assemblage and undesirable wear and tear of the matrices.

The invention overcomes these diificulties by 10 providing a third assembler belt to receive the matrices conveyed to the centre of the magazine by both assembler belts, and convey them in the usual manner in front of the assembler. In determining the speed of the two belts which receive the matrices directly from the magazine, one must proceed in such a manner that irrespective of the parts of the magazine at which the matrices are released, the matrix which is released first must definitely reach the assembler first; the speed at which the respective belt travels, must therefore be at least such that that part of the belt which is located beneath the most outward magazine channel when the respective key is struck, will reach the centre of the magazine by the time the operator strikes the next InJGermany February 4, 1932 1933, Serial-No. 652,459

key. The assembler belt leading to the assembler, however, can be run at a slower speed because the matrices are delivered on to its upper end, always in proper sequence; the said belt has therefore only to run at such a speed that every time a key is depressed, the belt has travelled about the length of one matrix. The matrices can thus be delivered slowly into the assembler, so that damage through violent contact will be avoided.

The drawing is a diagrammatic front elevation of the pertinent parts of a matrix composing and line casting machine according to one constructional form of the invention.

The matrices in the usual manner are guidededgewise in the magazine a and are released through the actuation of the keys of the keyboard 1), and the consequential operation of the escapement reeds c. The matrices then drop between the guides 01 on to the assembler belts eand f, the upper flights of which run from each side of the magazine towards the centre. The belts are guided over the two outer pulleys g and g and the two inner pulleys h and 71. The matrices therefore are conveyed towards the centre, and are deflected by a guide block 1' into adelivery chute k which directs them on to the third assembler belt m which travels around two pulleys n and o. The lower part of the assembler belt m, in the usual manner, is con--- tiguous to the bridge 11 and to the star wheel q which projects the deflected matrices into the assembler r.

The two assembler belts e and 1 must still run at a comparatively high speed, so that the matrices are conveyed towards the center and delivered into the chute 7c, definitely in the correct order. As they are thus in the proper order, the assembler belt 121. can be driven at a comparatively slow speed, so that the matrices will no longer be subjected to possible damage by the star wheel q when they enter the assembler.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-

1. Matrix composing and line casting machine in which the matrixes released from the magazine are guided towards a point below the centre of the magazine by means of two assembler belts from which they are delivered into the assembler,.characterized by the fact that the conveyance of the matrices from the assembler belts to the assembler is effected by means of a third assembler belt distinct from the other two.

belts and which is driven at a speed less than that of the two assembler belts.

2. Matrix composing and line casting machine according to claim 1, characterized by the fact that beneath the place where the two assembler belts are nearest to each other is located a short guiding chute which deflects the matrices towards the assembler and directs them on to the assembler belt which conveys them towards the assembler.

3. In a matrix composing and line casting machine, the combination with a magazine, two oppositely inclined assembler belts converging downwards towards a pointbelow the centre of the magazine and adaptedto receive the matrices released from the magazine, and as assem bler adapted to receive the matrices in order of composition, of a short chute receiving the matrices leaving the inclined assembler belts, and

a third inclined assembler belt adapted to r ceive the matrices from the short chute and deliver them to the assembler.

4. In a matrix composing and line casting machine, the combination with a magazine, two oppositely inclined assembler belts converging downwards towards a point below the centre of vthe magazine and adapted to receive the mated to receive the matrices from the short chute and deliver them to the assembler.
